Comment 5 for bug 1880198

Thanks Sebastien, I've posted this bug upstream as https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/issues/1057

I've also noted some peculiarities with respect to different clients:

- computer: host/sink/server volume remains constant until source/client goes to 0, then silent
- Android phone: sink volume constant until the lowest 10% on source, then the volume decreases in 4 increments.
- ipad: sink volume constant no matter what the volume on the ipad source.
